Fight Week Nutrition

A complete day-by-day plan from Monday through fight night — what to eat, when to eat, and how to arrive at the ring fully fueled

Fight week is the culmination of months of training. Everything comes down to executing a precise plan: making weight safely, rehydrating effectively, and arriving at the ring with your body fueled and your mind sharp. This guide walks through each day with specific meals, fluid targets, and practical advice tailored for Kun Khmer fighters competing in Cambodia and internationally.

This plan assumes a Friday weigh-in with a Saturday fight. Adjust the timeline if your weigh-in and fight are on different days. For same-day weigh-ins (common in domestic Cambodian events), the water cut must be much more conservative — no more than 1.5-2% of body weight — since rehydration time is limited. See the weight cutting guide for the full 4-week protocol leading up to this week.

Monday Through Friday

Pre-fight nutrition plan with daily targets

Monday

5 Days Out~2,280 kcal

Focus: Final hard training session — fuel for performance

Water: 45-50 ml/kg (3.2-3.5L for 70kg fighter)

Breakfast (6:00 AM)

550 kcal

Bai sach chrouk — 1.5 cups rice, 120g grilled pork, pickled vegetables

Post-training (9:30 AM)

380 kcal

Protein shake with banana and coconut water

Lunch (12:00 PM)

550 kcal

Samlor korko with rice — lighter portion than usual training days

Snack (3:00 PM)

320 kcal

Small portion of rice with 2 boiled eggs

Dinner (6:30 PM)

480 kcal

Steamed fish with ginger, 1.5 cups rice, steamed vegetables

Monday is typically the last day of meaningful training. Eat enough to fuel a quality session but begin the slight caloric reduction that continues through the week. If you are on weight, eat normally. If you need to lose 1-2 kg, maintain a moderate deficit.

Tuesday

4 Days Out~1,700 kcal

Focus: Light training — technique and visualization only

Water: 45 ml/kg (3.15L for 70kg fighter)

Breakfast (7:00 AM)

400 kcal

Kuy teav with lean pork — light broth, moderate noodles

Mid-morning (10:00 AM)

150 kcal

Fresh fruit — papaya, banana

Lunch (12:30 PM)

450 kcal

Grilled chicken with rice (1 cup) and cucumber salad

Snack (3:30 PM)

280 kcal

Rice porridge (bobor) with chicken — small bowl

Dinner (6:30 PM)

420 kcal

Steamed fish with vegetables, 1 cup rice

Begin reducing carbohydrate portions. Replace high-volume carb meals with protein-focused dishes. Training should be limited to light pad work, shadow boxing, and visualization. Save energy — your body is a weapon that needs to be charged, not depleted.

Wednesday

3 Days Out~1,310 kcal

Focus: Water reduction begins — light movement only

Water: 25 ml/kg (1.75L for 70kg fighter) — water cut begins

Breakfast (7:00 AM)

380 kcal

Scrambled eggs (3) with a small portion of rice, sliced tomato

Mid-morning (10:00 AM)

160 kcal

Small handful of almonds or cashews

Lunch (12:30 PM)

350 kcal

Grilled chicken breast (150g) with steamed vegetables — no rice

Snack (3:30 PM)

100 kcal

Apple or small banana

Dinner (6:00 PM)

320 kcal

Lean protein (grilled fish or chicken, 150g) with green vegetables

Water intake drops significantly. Carbohydrates are minimized to deplete glycogen stores and release bound water. You will feel hungry and possibly irritable — this is normal. Keep yourself occupied with light stretching, visualization, and rest. Avoid heavy physical activity. Monitor urine color — it will darken, but it should not become brown.

Thursday

2 Days Out~710 kcal

Focus: Deep water cut — rest and prepare mentally

Water: 15 ml/kg (1.05L for 70kg fighter) — sipping only

Breakfast (8:00 AM)

280 kcal

2 boiled eggs, small piece of chicken breast

Lunch (12:00 PM)

250 kcal

Small portion of grilled fish with leafy greens (no dressing)

Dinner (5:00 PM)

180 kcal

Small protein-only meal — 100g chicken or fish

This is the hardest day. Fluid intake is minimal and food is sparse. Stay in a cool environment to minimize sweating. Do not train. A short walk is acceptable but avoid anything that increases fluid loss beyond what the protocol calls for. If fighting Saturday, this is the peak of the water cut. Weigh yourself in the evening — you should be within 1-1.5 kg of your target.

Friday

Weigh-In Day (if fighting Saturday)~1,880 kcal (post weigh-in)

Focus: Make weight, then refuel immediately

Water: Sips only until weigh-in, then aggressive rehydration

Before weigh-in

0 kcal

Nothing or small sips of water if absolutely necessary

Immediately after weigh-in

80 kcal

Electrolyte drink (ORS), coconut water — begin sipping immediately

1-2 hours post weigh-in

400 kcal

Rice porridge (bobor) with chicken, banana, more electrolyte drinks

3-4 hours post weigh-in

550 kcal

Bai sach chrouk or rice with grilled chicken — moderate portion

6-8 hours post weigh-in

600 kcal

Amok trey with rice — familiar, balanced meal

Evening snack

250 kcal

Fruit, yogurt, or light carbohydrate snack

The moment you step off the scale, your sole focus shifts to rehydration and refueling. Sip fluids steadily — do not chug large volumes as this can cause vomiting and delay absorption. Prioritize electrolytes in the first 2 hours, then transition to balanced meals. By evening you should have consumed at least 3-4 liters of fluid. You will not fully recover all lost fluid, but you can regain 70-80% if you are disciplined with the protocol.

Weigh-In Day Protocol

Weigh-in day is the culmination of the entire weight cut. Your only job before stepping on the scale is to be at or under your target weight. Everything else — rehydration, refueling, rest — comes after.

Before the Scale

  • Wake up early and check your weight on a reliable scale
  • If you are on weight, take small sips of water to stay comfortable
  • If you are 0.5-1 kg over, a hot bath or light exercise in warm clothing can shed the last bit
  • Arrive at the weigh-in venue early to avoid stress
  • Weigh in wearing as little as permitted by the rules
  • If you miss weight, most sanctioning bodies allow a 1-2 hour window to try again

Immediately After the Scale

  • Begin sipping an electrolyte solution — have it prepared in advance
  • Your corner team should have your rehydration supplies ready at the venue
  • Do not eat solid food for the first 30-60 minutes — focus on fluids
  • Move to a comfortable location where you can eat and rest
  • Follow the rehydration protocol from the weight cutting guide
  • Avoid celebrating with alcohol — your body needs every drop of fluid for recovery

Day-of-Fight Nutrition

Precise timing around your scheduled fight time

4-5 hours before fight

Pre-fight meal

A moderate, familiar meal high in carbohydrates with moderate protein and low fat. White rice with grilled chicken or fish. Avoid anything heavy, spicy, or unfamiliar. This is not the time to experiment.

1.5 cups rice, 120g grilled chicken, small portion of steamed vegetables. ~520 kcal.

2-3 hours before fight

Light snack

A small carbohydrate-rich snack to keep blood sugar stable. Easy to digest and quick to clear the stomach.

A banana with a small amount of honey, or a piece of white bread with jam. ~150 kcal.

1 hour before fight

Final hydration and energy

Small sips of water or electrolyte drink. Some fighters take a small amount of honey or a glucose gel for a quick energy boost. Keep it minimal — a full stomach impairs breathing and movement.

200ml water or electrolyte drink, optional tablespoon of honey.

30 minutes before fight

Nothing

Stop all food and fluid intake. Focus entirely on warm-up, mental preparation, and the Twai Kru ceremony. Your body has the fuel it needs — trust the preparation.

Warm-up, visualization, and pre-fight rituals only.

Between rounds

Water and glucose (if needed)

Small sips of water during the corner break. Some fighters take a sip of electrolyte drink or a glucose rinse (swishing a sugary drink and spitting it out) to signal energy availability to the brain without adding fluid to the stomach.

A few sips of water. Glucose rinse if fatiguing.

Immediately after the fight

Begin recovery nutrition

Within 30 minutes of the fight ending, begin consuming fluids and simple carbohydrates. A protein shake with banana is ideal if available. Coconut water for electrolytes.

Protein shake, banana, 500ml coconut water. ~350 kcal.

Post-Fight Recovery Meal (1-2 Hours After)

After the adrenaline subsides, eat a full, balanced meal. Your body has been through extreme stress and needs calories, protein, carbohydrates, and hydration. Many Cambodian fighters celebrate with a favorite dish — lok lak, amok trey, or bai sach chrouk. This is the one meal of the week where you can eat freely. You have earned it. Drink plenty of fluids and continue rehydrating through the evening. If you sustained any cuts or significant trauma, prioritize protein-rich foods to support healing.

Mental Aspects of Fight-Week Eating

The psychological dimension of nutrition during the hardest week

Accept discomfort as temporary

Fight week hunger and dehydration are temporary. Remind yourself that thousands of fighters have gone through this process successfully. The discomfort peaks on Thursday/Friday and ends completely after you step on the scale. Reframe the discomfort as part of your warrior preparation — Kun Khmer fighters have been making sacrifices before battle for centuries.

Maintain your routine

Eat at the same times you normally eat, even if the portions are smaller. Keep your daily schedule as normal as possible. The structure of routine provides psychological stability when your body is under stress. Wake up at the same time, go to the gym at the same time (even if just to stretch), and maintain your evening habits.

Separate food from emotion

Fight week is not the time to eat for comfort, boredom, or stress relief. View food purely as fuel and medicine. Each meal has a specific purpose — to maintain muscle, to support recovery, or to prepare for the scale. This disciplined mindset is a core part of the fighter's mentality and extends beyond the kitchen into the ring.

Manage irritability

Caloric restriction and dehydration cause irritability — this is a physiological response, not a character flaw. Warn your family, training partners, and friends that you may be short-tempered during the cut. Avoid making important decisions or having difficult conversations during the final 48 hours. Use meditation, breathing exercises, or listening to music to manage your emotional state.

Visualize the post-weigh-in meal

Having a specific meal planned for after weigh-in gives you something to look forward to and provides a concrete endpoint to the restriction. Many experienced fighters have a ritual first meal — a favorite dish that they associate with the relief and satisfaction of making weight. In Cambodia, bai sach chrouk or a bowl of kuy teav are popular choices.

Trust the process

If you have followed the 4-week protocol and your weight has been tracking according to plan, trust that the process will work. Anxiety about the scale is natural, but panicking and doing something drastic (like an extra sauna session or skipping water entirely) is more likely to hurt your performance than help it. Stick to the plan.

“The fight is not just in the ring. The fight begins the moment you commit to a weight class and start preparing your body. A disciplined fighter controls what they eat, when they eat, and how they think about food. This discipline is the same discipline that keeps your guard up in round five when your arms are burning. It is all connected.”
